My brother and I have been doing quite a few three day fast-pack trips in the past three months. Our first trip we took the Iodine and Iodine Taste Remover Caplets. Then my brother bought the Hiker Pro. I must say, while hiking in the Shannandoa, George Washington National - and many other small state parks - I have never had such great tasting and pure water than what I drank from this filter. It was like a religious moment when we found cold water also. I must say, from using this product for three to four months now, I wont be buying any other water filters. Its great for fast-packing because of the low weight and packability, and also great because of the option of getting the quick connect for your water bladder which makes fill ups go twice as fast. I recommend getting this product!
